1. A dyadic radial coupler comprising:
an input port comprising a transmission line on an input layer of a printed circuit board (PCB), wherein the transmission line comprises a conductive portion;
a coaxial conductor, an end of the coaxial conductor operatively connected to the transmission line; and
a coupled port located at an opposite end of the coaxial conductor, wherein:
the dyadic radial coupler includes an at least partially annular conducting strip at one end of the coaxial conductor such that coaxial coupling of an RF signal is achieved between the input port and the coupled port, wherein a dielectric material intervenes between the conductive portion and a central conductor of the coaxial conductor.
